Question

Calculate the magnitude of force required in newton to produce a pressure of 28500 Pa on an area of 100 cm².

Answer 1

Step 1: Given data

Area, $A=100c{m}^2=0.01m^2$

Pressure, $P=28,500Pa$

Step 2: Formula used:

The formula for pressure can be given as,

$Pressure\left(P\right)=\frac{Force\left(F\right)}{Area\left(A\right)}$

Step 3: Finding force:

Putting all the values we get,

$$\begin{gathered} P=\frac{F}{A} \\ \Rightarrow F=PA \\ \Rightarrow F=28,500\times 0.01 \\ \Rightarrow F=285N. \end{gathered}$$

Hence, the magnitude of the force is $285N.$
